0bb2d96afe * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Enable 
absptr -> pcrel optimization for shared libs.
	Only create minimal .eh_frame_hdr if absptr FDE encoding in shared
	library cannot be converted to pcrel.

	relative.

	_bfd_elf_section_offset returned -2, skip, but make sure the
	relocation is installed.

before looking for .eh_frame_hdr section.

a5eb27e6ff * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): If new_size 
is 0, temporarily grow it to minimal CIE size.
	(_bfd_elf_write_section_eh_frame): If input .eh_frame section would
	end up empty, build a fake minimal CIE.

9e2a48988a * elf-eh-frame.c (struct cie): Add make_lsda_relative. 
(struct eh_cie_fde): Add lsda_encoding, lsda_offset,
	make_lsda_relative.
	(read_value, write_value): New.
	(_bfd_elf_discard_section_eh_frame): Inicialize
	lsda_encoding, lsda_offset and make_lsda_relative.
	(_bfd_elf_eh_frame_section_offset): If make_lsda_relative,
	request no dynamic reloc for LSDA field of FDE.
	(_bfd_elf_write_section_eh_frame): Handle make_lsda_relative.
	If a non-DW_EH_PE_absptr value is 0, don't adjust it by base
	or pcrel.  Fix address computation for DW_EH_PE_pcrel relocs.
	Update LSDA field if LSDA encoding is DW_EH_PE_pcrel, because
	. might have changed due to deleted FDE or CIEs.
